BENTLY NEVADA 330101-00-08-20-02-05 Extension Cable | 3300 Series Proximity System
Engineering Background
The Bently Nevada 3300 Series is the industry benchmark for continuous vibration monitoring in rotating machinery — turbines, compressors, pumps, and motors operating in critical process environments. The extension cable is the precision signal-transmission link between the proximity probe and the proximitor/driver, forming the third leg of the three-component eddy-current sensing chain. Signal integrity across this cable directly determines measurement accuracy, alarm reliability, and machinery protection system performance.
Product Positioning
The 330101-00-08-20-02-05 is an OEM-specified extension cable engineered for the Bently Nevada 3300 Series proximity transducer system. It is designed for procurement engineers and reliability teams who require drop-in replacement parts with full system compatibility — no recalibration, no signal offset correction, no compromise on SIL-rated protection loops.

System Architecture & Signal Flow
The 3300 Series proximity transducer system operates as a three-component eddy-current chain:
- Proximity Probe (e.g., 330103 / 330104 series) — generates the high-frequency electromagnetic field at the shaft surface
- Extension Cable 330101-00-08-20-02-05 — transmits the raw oscillator signal from probe tip to proximitor with minimal loss and zero impedance mismatch
- Proximitor / Driver (e.g., 3300 XL proximitor) — conditions the signal and outputs a calibrated -24 VDC linear DC voltage proportional to gap distance
The output signal feeds directly into Bently Nevada 3500 Series rack monitors or equivalent machinery protection systems for alarm, trip, and trending functions.

Technical FAQ
Q: Can this cable be used with non-Bently Nevada proximitors?
A: Not recommended. The cable is impedance-matched to the 3300 Series system. Use with third-party drivers may introduce calibration errors and void system certification.
Q: What is the maximum cable run for the 3300 Series system?
A: Bently Nevada specifies fixed probe + extension cable combinations. The total system cable length must match the proximitor calibrated range — typically 5 m or 9 m total. Confirm your proximitor calibration range before ordering.
Q: Is this part available with ATEX documentation?
A: Yes. ATEX and IECEx certificates are available upon request. Please specify your installation zone classification when ordering.
Q: Do you offer expedited shipping for shutdown/turnaround situations?
A: Yes. Contact us directly at +0086 19859288691 for emergency procurement support. We maintain stock for critical-path orders.
Q: Can I return the part if it does not match my system?
A: Yes, within 30 days of receipt in original, unused condition. Please verify the part number against your system documentation before ordering.
